Given: Area of a square print photo = 9 in^2
Find the perimeter.
Formula for perimeter = 4l
Solution:
Find first the measure of length of the squares, with the given area
Formula for area: a = l^2
Solve for the equation of l
a =l^2
l = √a
l=√9
l = 3
Now that the value of l is determined, the perimeter can be solved.
Perimeter = 4l
Perimeter = 4(3)
Perimeter = 12 inches
